3D OLV Training Intervention for Pediatric Anesthesia Trainees

Withdrawn

• Conditions: Anesthesia
• Interventions: Behavioral: OLV technique on tracheo-bronchial model

• Registration Number: NCT03929315
• Lead Sponsor: Clyde Matava

Brief Summary

One lung ventilation (OLV) in neonates and children is an advanced skill that is necessary for delivery of safe and quality anesthetic care. The current model of training for OLV in the paediatric patient is composed of the apprenticeship model. Trainees learn the techniques of doing the procedure when they encounter a case that allows for it. The model of training is often inadequate for mastery of skills such as OLV as children in this population often have severe debilitating disease often requiring the most experienced anesthesiologist to perform OLV. This limits the training exposure of anesthesia trainees.

Detailed Description

Each participant will be subjected to three learning sessions on a 6 year old tracheo-bronchial model. Learning will either be spaced (1 week between learning/testing sessions) or non-spaced (30 minutes between learning/testing sessions). They will have 20 minutes to practice on this model before they are asked to perform the OLV on a younger tracheo-bronchial model (2 yrs, 3 months, 6 weeks). After each testing session, the participants will be provided with feedback. After all learning/testing sessions take place, the participants will be asked to complete a retention test on the 6 week old model six weeks after their last session.
